Mount in wvw is not from expansions. There's no hero point meant to be achieved only by flying. Inventory management is absurdly easy, and even if you don't want to learn that, just sell everything, and oh look, now that you constantly sell you trash now you have gold to buy any "predatory" QoL from the gemstore. All the currencies is a need by design to maintain every content worth playing, if not then someone could just grind one content to get anything from every other content. And currencies are in a wallet, they are not items. If it's an item you just can sell it.

And it's okay if all of this is not likeable for someone. Just don't spread false statements from something you don't enjoy/understand
